To use PTO speed control in Preset Mode (Factory
Setting) do the following:

1. Engage the PTO

2. Select PARK (P) or NEUTRAL (N) range. Apply the

parking brake if NEUTRAL (N) is selected. Torque
Converter Clutch (TCC) is not available in
NEUTRAL (N) and is available only in PARK (P)
when engine speed is above 1100 rpm.

3. Make sure your foot is off the brake pedal 

(and off the clutch on vehicles equipped with 
a manual transmission).

4. Select the desired engine speed for PTO operation.

Read the following preset mode information
regarding operation.

Preset Mode: PTO speed control mode is used for
stationary applications. (PTO will remain engaged while
mobile in the preset mode, however PTO set and resume
speed controls will be inoperative). This mode provides
a default standby speed of 800 or 850 rpm (depending
on the engine/transmission combination) and
two default PTO control speeds which follow:

1. PTO Set Speed of 1250 rpm, or

2. PTO Resume Speed of 1700 rpm.

Please note that the standby speed (800/850 rpm) is 
not to be used as a PTO control speed. Vehicles not
equipped with cruise control will not have the resume
speed capability.

To use PTO speed control in variable mode 
(while mobile) do the following:

1. Engage the PTO.

2. Vehicle speed must be greater than 5 mph.

3. Make sure your foot is off the brake pedal 

(and off the clutch for vehicles equipped with 
a manual transmission).

4. Select the desired engine speed by using the foot

pedal, and select SET on the PTO switch or the
cruise control.
